Thread: Java Count Help

I have created a basic array and loop as shown below but I am trying to work out how I would go about coding the end results, for example….

After 6 loops array1 “Won” 4 times and array2 “Won” 2???

Any help would be greatly appreciated.

import java.util.Random;

public class Main {

public static void main(String[] args) {

int[] array1 = {10, 6, 8, 9, 7, 12, 7};
int[] array2 = {7, 6, 9, 5, 2, 8, 11,};

Random rand = new Random();

for (int i = 1; i < array1.length; i++) {
int randomIndexToSwap = rand.nextInt(array1.length);
int temp = array1[randomIndexToSwap];
array1[randomIndexToSwap] = array1[i];
array1[i] = temp;
}

for (int j = 0; j < array2.length; j++) {
int randomIndexToSwap = rand.nextInt(array2.length);
int temp = array2[randomIndexToSwap];
array2[randomIndexToSwap] = array2[j];
array2[j] = temp;

I have created a basic Array and loop as shown below but I am trying to work out how I would go about coding the end results, for example….

How does one code the number of random integers displayed after the loop?

I.E. "player 1 won 0 Rounds".
I.E. "player 2 won 6 Rounds."


I.E. "player 1 won 2 Rounds".
I.E. "player 2 won 4 Rounds."

I.E. "player 1 won 1 Rounds".
I.E. "player 2 won 5 Rounds."


etc........

Any help would be greatly appreciated.

To track how many times each array "won" after 6 loops, you can use counters and compare the elements of each array after shuffling. Here's how you can modify your code to achieve that:

```java
import java.util.Random;

public class Main {

public static void main(String[] args) {

int[] array1 = {10, 6, 8, 9, 7, 12, 7};
int[] array2 = {7, 6, 9, 5, 2, 8, 11};

Random rand = new Random();

int array1Wins = 0;
int array2Wins = 0;

for (int loop = 0; loop < 6; loop++) {
for (int i = 1; i < array1.length; i++) {
int randomIndexToSwap = rand.nextInt(array1.length);
int temp = array1[randomIndexToSwap];
array1[randomIndexToSwap] = array1[i];
array1[i] = temp;
}

for (int j = 0; j < array2.length; j++) {
int randomIndexToSwap = rand.nextInt(array2.length);
int temp = array2[randomIndexToSwap];
array2[randomIndexToSwap] = array2[j];
array2[j] = temp;
}

int sumArray1 = 0;
int sumArray2 = 0;

for (int num : array1) {
sumArray1 += num;
}

for (int num : array2) {
sumArray2 += num;
}

if (sumArray1 > sumArray2) {
array1Wins++;
} else if (sumArray1 < sumArray2) {
array2Wins++;
}
}

System.out.println("After 6 loops, array1 won " + array1Wins + " times and array2 won " + array2Wins + " times.");
}
}
```

In this code:

1. I've added two counters, `array1Wins` and `array2Wins`, to keep track of how many times each array wins.
2. I've wrapped your existing code in a loop that runs six times (as you mentioned "after 6 loops").
3. Inside the loop, after shuffling both arrays, I sum up the elements of each array.
4. Then, I compare the sums and increment the respective counter if array1 wins (`sumArray1 > sumArray2`) or array2 wins (`sumArray1 < sumArray2`).
5. Finally, I print out the results after the loops are done.

After 6 loops, it's evident how Java programming assignments can benefit from thorough testing and analysis. For those seeking further help with Java assignment, exploring additional resources like programminghomeworkhelp.com could provide valuable insights and guidance.
